T'ZVI E FOR DRIVING MOTOR AGRICULTURAL MACHINES.

Specification of Letters Patent.

Application filed March 15, 1909. Serial No. 483,667.

To all/whom it may concern: Be it known that I, ALEXANDER JnszEN- SZKY,a subject of the King of Hungary, re siding at Nogradktivcsd,Austria-Hungary, have invented certain new and useful Improvements inDevices for Driving Motor Agricultural :Machines, .such as Ha'rrows,Rollers, Sowing and Reaping Machines, and the Like, of which thefollowing is a specification. I

The present invention relates'to a device for'driving motor agriculturalmachines, such as harrows, rollers, sowing and reaping-machines and thelike and the object of the invention is, on the one hand, to increasethe breadth and thereby the efiiciency of such agricultural maehines,and, on the other hand, to do away with the draft cattle. Both saidobjects are of great importance considering the present state ofagriculture, the difiiculties to obtain land laborers and the continuousincrease of working expenses which all necessitate the immediateutilization of favorable weather which however is only possible withmachines of Very great efiieiency. On the other hand, the remunerativeutilization of fruit-culture requires cattle-(ailture, so that anyimprovement which permits to reduce the draft cattle increases thenumber of useful cattle and consequently the rentability of thefarm-yard.

Agricultural machines are used only periodically and for a short time,so that, if the motor were combined with the machine, the cost ofconstruction would be unnecessarily augmented. The motorcars put beforethe machines for dragging the same along are very heavy and thereforevery unpractical. For these reasons the driving of agricultural machinesby motors 'has not been adopted with the exception of the steam-plow andthe standard locomobiles for threshing-machines.

The present invention does away with all the above mentionedinconveniences as the motors used for driving agricultural. ma-' chinesare light motorcycleswhich are disposed at both sides of the machine andmu led with the same so thatthey can be easi y uncoupled. Themotorcycleswhich are arranged at the sides of the machine do not'damage' the fruitnor beat down the loose soil and they can further be used at any timeand with anyagricultural machine whatsoever.

for example, the frames of the cycles can be coupled with the frame ofthe agricultural Patented Jan. 25, 1910.-

machine or the frames of the motorcycles can be coupled with the drivingshaft of the machine or the driving shaft of the cycles may be coupledwith the driving shaft of the machine, it being absolutely immaterialfor the feature of the present invention in what manner the coupling ofthe machine and the motorcycles be effected. It is however essentialthat the coupling device can vbe easily removed and that the motorcyclesbe arranged at the side, either at one or at both sides, of the machine.

Instead of motorcycles light motorcars could be used. The samearrangement can be used for driving street-cleansing-machiues andwater-carts. Y

In the accoln anying drawings the preferred form of t 1e invention isshown.-

Figure l isan axial projection representing a sowing machine with thedriving englues. Fig. 2 is a diagram in ground plan. 1

The two motorcycles a and b are connected the one with the other bymeans of rods 6 which are fixed each with one end to theframe of itsmotorcycle. Said rods e have a.

certain number of holes (I destined to receive the screw-bolts c withtheir nuts which serve to adjustably fix the free end of one rod 6 uponthe free end of the other rod. The machine to be driven, in the exampleshown a sowing machine f, is coupled with the rods (2 by means of arms 9which have fork shaped front ends so as to embrace said r'ods upon whichthey are fixed in any suitable and convenient manner.

I claim I An improved device for driving agricultural machines such asharrows, rollers, sowingand reaping-machines and the like comprising incombination with the agricultural machine to be driven, two motorcycles,one at each end of said machine, a rod fixed with one end on the frameof the one motorcycle and having a certain number of holes and a cycles,substantially as described. and shown rod hxed with one end on the frameof the other motorcycle and having a certain nun1- ber of holes, screwbolts and nuts for adjustably connecting the free ends of said rods andforkshaped arms projecting from the front side of the agriculturalmachine to be fixed upon said rods connecting said motorand for thepurpose set forth.

J 11 Witness whereof I have hereunto set my hand in the presence of twowitnesses.
